Similar letters ofreference indicate like parts.

This invention relates to a new and useful improvement in that'class of cnltivators in which the plows that work by the sides ofthe rows of plants are capable of being adjusted laterally, in order' that they may coliform to the sinuosities of the rows.

The object of the invention is to'ohtain a lsimple and efficient device for the purpose specified, and one which may be opcratcdhy the driver withthe greatest facility.

A represents a rectangular frame, which is mounted on two wheels, B B, and has a draftpole, G, attached to il'.

D D are two horizontal shafts, which are in 'line with each other and have their bearings, in

uprights E, attached to a cross, F, of frame A.

To each of these shafts D D thereis attached by a pivot, a, a plow-standard, G, the

pivots passi ng through the upper ends ot" the latter. These plow-standards arc connected` by a bar, H, and the lower endv of each standard has a plow, I, attached to them, ot' the ordinary form. One of these plow-standards G has a metal loop, J, attached to -its side, thronegh which the front end of a bent red, 1C, passes, said rod being fitted in a hearing, i1., attached te the under side oi' the cross-bar i?, and having a lever, L,secared te its hack end, said lever project-ing from each side of the rod and having a stirrup, M, secured to each end of it to receive the feet ot' the driver who is on seat N at the rear ot' the frame. I

Each plow-standard G is connected by a cord, O, to a shaft, F, placed transversely in the frame A, and having lan arm, Q, project ing from it, which arm is connected by a har,

plants, and said plows may also be raised up:

out of the earth, when required, by drawing hack the lever S, which is within convenient; reach of the driver.

To each side of the frame VA there is attached by a pivot, c, a plo\vstandard,T, havingzplows -U secured to'their lowcr ends. These standards are allowed to work freely on the pivots c, and their lower ends are connected by cords-d to the 'shaft P. It will he seen, therefore, that the plows U will be raised simultaneously with the plows I.A

The plows U are designed for plowing and eradicating thc weeds between the rows of plants. I

Te claim as new and desire to secure by 'The combination of the rising and falling or vertically-adjustable plcws U, with the rising. and falling and laterally-adjustable plo'ws I, when the latter are pivotcd to shafts D D, and connected to the shafts I', so as to rise simultaneously.with the plows U on the turninn; of the shaft P, asand for the purpose herein sct forth.
